On October 4, 2014, the Blitz announced they were joining X-League Indoor Football[3] for the 2015 season. Shortly after, the team was removed from the X-League website, and was no longer affiliated with the X-League. On October 15, 2014, the Blitz joined American Indoor Football (AIF), following former CIFL team, the Sting.[4] The Blitz finished the regular season 6-2, earning the 3 seed in the AIF playoffs. They defeated the 2nd seeded Saginaw Sting 63-45 in the AIF semifinals, earning a berth in the 2015 AIF Championship Game. The Blitz traveled to York, Pennsylvania to take on the York Capitals for the AIF crown. The Blitz fell to the Capitals 30-58.[5]

The Blitz played their second season in the AIF as members of the Northern Division. The team earned a 3-3 record but cancelled their final game of the season at the West Michigan Ironmen and team owner Mike Oliver immediately announced that the team was for sale. After the season ended, the AIF removed the Blitz from its team listings.
